Definitions
- the present invention relates to the coupling of pipes which are malleable and deformable such as pipes made of stainless steel, copper and other metals.
- connection member including a first deeper groove portion being adapted to contain an O-ring and a second adjacent portion being adapted to have crimped into it a portion of a telescopically engaged malleable pipe.
- the connection member having a relatively thick wall is received internally within the malleable pipe and significantly restricts the flow passage through the pipe.
- the present invention proposes an arrangement which is believed to be practicable and effective at providing reliable fluid tight joints.
- a method of connecting two malleable pipes comprising locating an end portion of one pipe inside the end portion of the other pipe with an O-ring located between the end portions, and using a crimping tool to apply inwardly directed crimping forces in a. radially inward direction around the O-ring and in a manner to cause radially inward deformation of both pipe portions immediately adjacent each side of the O-ring whereby the O-ring is deformed and partially flattened to establish a fluid tight seal between the pipes.
- the deformable O-ring is one of two axially spaced O-rings and application of the crimping means involves a first crimping operation being applied across a first of the O-rings so as to form a crimp between the pipes on both sides of the first O-ring, and a second crimping operation being applied across a second of the 0 rings so as to form a crimp between the pipes on both sides of the second O-ring.
- the invention is generally applicable to pipes of malleable material; an especially important application of the invention is to stainless steel pipes which have many advantages in terms of inertness and capable of being worked.
- the invention has been tested with stainless steel pipes having relatively small wall thicknesses, i.e. generally less than 1 mm and typically 0.7 mm and grade 304 or 316 stainless has been successfully trialed.
- the crimping force can be applied uniformly around the periphery of the pipes, some discontinuity in the applied crimping force or the crimping means itself can be advantageous in some embodiments and in particular those where resistance to relative rotational motion of the two pipes about their axes is desired.
- the crimping force is preferably provided by a crimping die which could be of the form for hand tool having two die carriers.
- Another aspect of the invention consists in a kit or combination of parts comprising first and second pipes adapted for interconnection in accordance with the first aspect of the invention and flexible sealing means in the form of O-rings for cooperation therewith.
- Another aspect of the invention consists in pipe joints made utilising any form of the invention as described above.
- FIG. 1 is a cross section view of two pipes crimped together in accordance with one embodiment
- FIG. 2 is a side view partly in section of one embodiment of a tool for use with the embodiment of FIG. 1;
- FIG. 3 is a plan view of the tool of FIG. 2;
- FIG. 4 is a front view, partly in section, of the tool
- FIG. 5 illustrates a front view of an alternative tool
- FIG. 6 illustrates a side view of the tool of FIG. 5
- FIG. 7 is a cross-sectional view through a second and preferred embodiment of the invention showing a coupling between two pipes with only one of the two required crimps performed on the coupling;
- FIG. 8 is a partially cross-sectioned front elevation of a crimping tool particularly adapted for use in the embodiment of FIG. 7;
- FIG. 9 is an end elevation of the tool of FIG. 8.
- FIG. 10 is a schematic front elevation of an alternative crimping tool adapted to be hand operated.
- FIG. 1 there is illustrated, in section, two stainless steel pipe ends 1 and 2 .
- a cylindrical rubber sheet 3 or other suitable sealant which is designed to act as an O-ring device and seal the connection between the two pipes 1 and 2 .
- the apparatus of the preferred embodiment is designed to produce a series of circumferential crimps 4 , 4 a around the stainless pipes 1 and 2 so as to pinch the rubber sheet 3 between the two pipes and to strongly couple together the two pipes 1 and 2 .
- FIGS. 2-4 there are illustrated plan views, partly in section, of one form of the apparatus of the preferred embodiment 10 , FIG. 2 illustrating a side plan view, FIG. 3 illustrating a top plan view, and FIG. 4 illustrating a front plan view.
- the apparatus 10 includes a handle 11 which has a semi-circular annulus cross section and is designed to fit along, in the axial direction, a suitably sized portion of pipe.
- the handle 11 is pivotally hinged to a body 12 by means of hinges 13 , 14 .
- the body 12 can be separated into two portions 16 , 17 which are separable and designed to be placed around the pipe to be crimped.
- bolt screws 19 , 20 are inserted through a corresponding cavity in each of the portions 16 , 17 .
- the bolts 19 , 20 have a thread which is reciprocated by a reciprocating thread within body portion 17 .
- the body 12 can be placed around a pipe, with the bolt screws 19 , 20 utilized to initially provide a tight fit for the two portions 16 , 17 around the pipe.
- the protuberances 21 , 22 do not extend fully around the circumference of the pipe and there is provided a small space 23 , 24 for the pipe to bulge at the side.
- the space between the two body portions 16 , 17 as they are brought together can be utilised to “pinch” the sides of two pipes.
- the resulting crimp therefore is not totally symmetrical around the pipe and has two side bulges.
- the non-symmetrical crimping is significant in that the resulting coupling resists rotational movement of one pipe end 2 relative to the other pipe end 1 .
- FIGS. 5 and 6 there is illustrated an alternative embodiment of an apparatus suitable for crimping pipes together.
- FIG. 5 illustrates a front plan view of the alternative apparatus
- FIG. 6 illustrates a side plan view of an alternative apparatus.
- the alternative embodiment 30 includes two block portions 31 , 32 each having a corresponding blade portion 33 , 34 .
- Each of the block portions 31 , 32 is placed within a slotted side bracket 36 , 37 .
- a further block portion 39 is also provided and contains an aperture and thread designed to receive a suitably sized screw bolt 40 .
- the screw bolt 40 can be of varying length. In use, the screw bolt 40 is tightened and the end 41 engages the block portion 31 forcing it towards the block portion 32 . Before tightening, the pipes are placed resting on blade portion 34 , with the subsequent tightening of bolt 40 resulting in blade portions 33 , 34 being forced against a pipe and thereby producing a crimp coupling as hereinbefore described.
- FIG. 7 shows schematically the crimped coupling. After sliding assembly, a crimping tool is applied. Although a single crimping tool to form both crimps could be utilised, equally each crimp can be separately formed.
- the outer tube 70 is inwardly crimped in two stages with the crimping tool during each stage locating across one of the pair of O-rings 74 thereby causing crimping at corresponding annular zones 75 , 77 and 76 , 78 .
- This deformation causes pressure to be applied to the O-rings which typically deform and flatten being of low compressible material.
- FIG. 8 illustrates an option of a die arrangement which is not continuous around the tubes thereby providing greater deformation in some points than others. This substantially prevents relative rotation of the tubes and this can be advantageous in some applications.
- the embodiments of FIGS. 8 and 9 rely on two screws 80 which pull together the die portions 81 and 82 .
- FIG. 10 shows an alternative tool 100 having a pair of arms 101 and 102 which is squeezed together manually.
- the opposite ends of the tool comprises crimping arms 103 and 104 carrying crimping dies 105 .
